A method of controlling the operation of a fuel injector (12) of a fuel system using a control system of the type comprising an accelerometer (14) associated with an engine (10) and arranged to sense vibrations thereof, and monitor means (16) arranged to monitor the output signal of the accelerometer (14) to detect vibrations of the engine (10), is described. The method comprises applying a drive pulse to the injector (12), using the monitor means (16) and the accelerometer (14) to determine whether or not the application of the drive pulse results in combustion in the cylinder of the engine associated with the injector (12), and modifying the duration of the drive pulse to determine the minimum pulse length which must be applied to the injector (12) to cause combustion. <IMAGE> |
